Please help: Browser keeps redirecting (hijackthis! log inside)

Starting today, my browser (ie6) windows randomly redirect to http:/// (blank page), even when a window has been minimized for a few minutes. Adaware found 16 things and fixed them (can't remember what they were), Spybot found nothing, and so far AVG is finding nothing. It smells like a hijacker to me, but as I'm not familiar with Windows ME system files, I'm not sure if anything looks awry. Any help is appreciated greatly. Thanks!
